Catheterization of the radial or brachial artery in neonates and infants.

Background: In neonates and small children, percutaneous insertion of arterial catheters may be very difficult because of the small diameter of the arteries. Multiple attempts at cannulation are common and may be a predictor of serious adverse events following arterial cannulation. As an end artery, the brachial artery is usually not recommended for cannulation.

Epidural block with ropivacaine and bupivacaine for elective caesarean section: maternal cardiovascular parameters, comfort and neonatal well-being.

Objective: To determine cardiovascular effects and neonatal outcome of ropivacaine 0.75% and bupivacaine 0.5% for elective epidural caesarean section.
